We call up with half of the power couple in France at the party at the advertising festival looking chic in a white and gold fitted dress.

I think when it kind of slipped it was in Florence we really wanted that surprise for our guests and hoping to have everyone at versailles anticipate tell them it's not in Paris, it's in Florence but a couple people -- so hard to keep secrets these days. It was really intimate. It was justur closest closest friends and family the whole week. It was just so special. Reporter: Special and record-breaking.

Reporter: The wall, a custom-made creation of white gar dean Nast, peonies and roses was a wedding surprise from the groom, a running theme in their lives. On mother's day, I mean there was a note on my door because he was out of town, he was there in Florence trying to, you know, figure out the whole wedding stuff and I slept in the baby's room and so there was a note on my door when I woke up say go outside and there was this whole wall of flowers and it was so special and I didn't know that he was, you know, making the same thing they wedding.
